Technology and R&D

A research team in India developed a passive solar-panel cooling method using a thin, still layer of seawater placed over the module surface. Tests showed that while a thick water layer sharply reduced energy output, a thin 5 mm layer lowered module temperatures and increased daily energy generation by up to 8.86%.

The Japanese conglomerate has deployed its Panasonic HX hydrogen solution at its facility in Munich. The system uses an AI-based energy management system that reportedly makes battery storage unnecessary.

An international team of researchers completed a preliminary techno-economic study on the global potential for offshore floating PV (OFPV). The results provide project cost benchmarking, country-specific economic assumptions, and a global assessement of offshore solar’s levelized cost of electricity (LCOE).

The two-terminal perovskite–silicon tandem solar cell was fabricated through a chemical polishing method that selectively removes residual lead(II)iodide from the perorvskite film in the top cell. This targeted interfacial engineering improved uniformity and stability, enabling a certified 31.71% efficiency and enhanced long-term performance.

Australian solar distributor OSW Group has enhanced its free solar, battery design and installation business tool, GreenSketch version 3.0 with new AI-powered features, that simplify and accelerate workflows.

Omniflow has developed a line of hybrid solar-wind streetlights. It offers optional solutions to integrate for security, phone recharging, and Internet of Things applications.

UK energy regulator green-lights transmission network operator budgets for five-year period. Initial budget of GBP 10.3 billion ($13.7 billion) approved with an upper-bound estimate of GBP 70 billion transmission investment by 2031. At least GBP 44 billion of transmission spend has already been committed, according to the regulator.

SMA Solar Technology announces the commercialization in Europe of its new MVPS-9200 medium voltage station in a 12-meter containerized version for battery energy storage systems (BESS) and large-scale photovoltaic power plants.

Chinese researchers have proposed a new methodology for designing utility-scale solar power projects in mountainous regions. They simulated a 386.4 MW solar farm near Pu’er, a city in southern China located 1,037 meters above sea level.

German start-up SPH has installed its ThermBooster heat pump at Philip Morris International’s Italian factory, producing high-temperature steam at 139 C. The system boosts energy efficiency, cuts gas use by up to 50%, and recovers 20–30% of water from exhaust.
